    I have a 96 IH 4700 with T444e, It had an electrial fire and fried the main Engine harness, after repairing it will only start with either then runs OK for 10 seconds & starts to miss then Eng light comes on. I read the codes & it has 12 of them. I tried to reset the codes with no luck. I'm sure the fire fried the ECM.

    My question is I have read that an ECM from a power stroke will work, is that true or did I mis understand? If yes does anyone know what years would fit?

    Yes its mounted on fire wall. Codes are:
    113 B+ High (Which i checked & its correct)
    115 Coolant temp sig out of range
    221 Speed command switchcircuit fault
    222 Brake switch fault
    224 Keep alive Memory corrupt
    251 Glow plug output circuit test failed (there was a glow plug issue before the fire)
    312 Eng oil temp signal out of range
    332 Injector control pressure above spec engine off
    333 Injector control press above/below spec
    543 Injectro drive module faults not recieved
    615 Programmable Parameter KAM Corrupt Fault
    622 Eng using field default rating


    Lots of codes, it starts with Either runs 10 seconds then seemes to go into a "Limp Mode" runs rough but runs.
    I have also check & replaces the 2 ECM power relays

    The 543 is what I would focus on. I think you have a 3 box system, meaning the ECM and Injector drive Module are two different boxes. Sounds like the IDM isn't booting up or damaged. I have rewired fire damage before, it can be quite a mess. You will need to do some trouble shooting to make sure the IDM is getting power and ground and communicating with the ECM.

    all of the damage was on the mail engine harness where it crosses under the block to the starter side. The ECM to ICM harness was untouched. Do you know if the "Hold diagnostic button in turn key on hit throttle 3 times" method would clear the codes on this model?

    I don't know of any way to clear the codes is your model without a laptop. The newer HPV models you can. You can tell which ones are active or inactive however. The active codes are codes that are happening right now. Just key on and after a couple of seconds hit the diagnostic button.
    Here is the sequence;

    The fault codes are read by counting the number of light flashes. The following sequence occurs:


    • The "Oil/Water" light will flash one time. This indicates the beginning of Active fault codes.
    • The "WARN ENGINE" light will flash repeatedly signaling the active fault codes. All codes are three digits. The number of flashes should be counted in sequence.
    • At the end of each digit of the code there will be a short pause. Three flashes and a pause indicates the number 3. The code 232 will be sent as two flashes, (a pause), three flashes, (a pause), and two flashes.
      If there is more than one code being sent, the "OIL/WATER" light will flash once indicating the beginning of another active fault code. The code 111 indicates "NO FAULTS".
    If no further Active fault codes exist, the "OIL/WATER" light will flash twice, indicating the beginning of "INACTIVE CODES". The "WARN ENGINE " light will then flash the "INACTIVE CODE"(s) present. If several "INACTIVE CODES" are present, the "OIL/WATER" light will flash once between each of the fault codes.
    When all of the stored fault codes have been sent, the "OIL/WATER" light will flash three times indicating "END OF MESSAGE".
    If it is necessary to repeat transmission of fault codes, press the STI button and all stored codes will be retransmitted as described previously.
